CHARLES MICHEL DALY, or NEW YOItK, N.- Y.

i WATER-HEATER.

Be it known that 1, CHARLES MIOHELHDIALY, a citizen of the United States, and a resident of the city of New York, borough of Man hattan, in .the county and State of New York, have invented a new and Improved Water- Heater, of which the following is a full, clear,

and exact description.

The invention relates to means for heating water in a receptacle as it may be required, and has for its object the provision of a com pact portable water-heating device of novel construction, which may be floated in water to be heated in a bath-tub or basin and which in service will quickly heat thewater, a further object being to so'construct a water-heating device that it, while floating in the water it is to heat, may be supplied with gaseous fuel from a source of gas-supply near the water-holder, which may be a fixed basin or a bath-tub. 1 The invention consists in the novel construction and combination of parts, as is hereinafter described, and indicated in the claims.

Reference is to be had to the accompanying in which similar characters of reference indi- 'cate corresponding parts in both figures.

Figure 1 is a plan view of the device; and Fig. 2 is a sectional side viewsubstant'iallyon the line 2 2 of Fig. 1, showing the device floating in a body of water. I

The heat-radiator comprises a preferably sheet-metal shell5, which, as shown, is in the form of a vessel having a cylindrical side wall j and closed at the normally lower end by a flat bottom wall 5*. I

A float 6 is mounted upon the shell 5, near the upper end of the same, said float consist+ ing of a ring which may have a circular or angular periphery.

- The float 6 may be of cork or light wood and has suflicient area to adapt it to buoy the shell 5 and the heating means contained therein, so that the preferably open top of the shell will be supported above a. body of water A,

which may be held in .a bath-tub, a washbasin, or other receptacle wherein water is to be heated. Within the shell 5 a plurality of ring-shaped spiral coils 7, formed of wire of 'a suitable gage, are placed, these coils having .close contact with the inner surface ofthe side and bottom walls of said shell and also with each other, as is plainly shownin Fig. 2.

A heater for the coils 7 is provided embody- S pecification of Letters Patent." Application filed. Apri126, 1905. Serial No. 257.446-

. ing a tube bent at a, so asto afford a depending member 8. The-horizontal portion 80f the. bent tube is formed with a nozzle end having reduced diameter in its bore, as indi cated by full and dotted lines in Fig. 2 at b,

forming a jet-orifice for the inflow of gas to the burner.

' Near the nozzle end 6 a plurality of perforations c are formed in the wall of the horizontal portion 8 for the, inflow of air, and a sleeve d is mounted slidably on the tube and maybe moved toward the jet-nozzle band cover anyv number of the perforations a. .In the closed lower end of the depending section 8 a fine perforation e is formed, and, as

tubular burner-section, as is shown in Fig. 2,

whereby the burnercomplete is supported in operative position for use, as may be desired.

A'pliable hose of ordinary style (shownpartially at 10 in' the drawings) is connected with the nozzle end 7) of the burner-tube portion 8, and thence extends to a gas-fixture (not shown).near the burner-tube and is therewith connected when the device is to be used for water-heating purposes.

' Assuming that the'bodyiof water A is contained in a bath-tub or washbasin, the heater device if placed therein will float and the shell 5 be immersed therein upto the float 6. Upon turning gas under pressure into the hose 10 and lighting the jet of mixed gas and air that issuesfrom the perforation e, and properly adjusting thejsleeve 41, so that air in proper volume will mix with the gas, a blue flame having intense heat will be projected from the heat the wire coils 7 The intimate contact of the pluralityof wire coils? with each other and upon the shell 5 will radiate the heat of the flame issuing at e from the burner-jet and transmit the heat'to the shell 5, which in turn will raise the temperature of the body of wa- I ter A, so that in a short time it will be warmed sufliciently for lavatory use. A. wire ring 5 may be loosely secured on the shell 5 at its lower end of the burner-body and quickly upper edge, which will afford convenient means for hanging up the heater device on a wall or other support when not in use. 7

It is obvious that the improvement may be used to heat water for laundry purposes and for heating water to wash dishes or general cleaning purposes and in service is a very convenient and reliable substitute for other means for heating water or other liquids.

Having thus described my invention, I claim as new and desire to secu re by Letters Patent- 1. A heater for liquids, comprising a shell of thin metal having a closed bottom, and adapted to be partially immersed in the liquid, a gas-burner mounted on the shell and extending thereinto, a plurality of ring-shaped coils of wire arranged in the space between the side and bottom walls of the shell and the burner, and means for maintaining the shell at a predetermined level in the liquid.

2. A heater for liquids, comprising a shell of thin metal having a closed bottom and an open top and adapted to be partially immersed in the liquid, a gas-burner mounted on the shell and extending thereinto, and a plurality of ring-shaped coils of wire arranged in the space between the side and bottom walls of the shell and the burner.

3. A heater for liquids, comprising a shell of thin metal having a closed bottom and adapted to be partially immersed in the liquid, a gas-burner comprising a tube having a horizontal portion connected to the edge of the shell, and an angular portion extending to a point near the bottom thereof, and a plurality of ring-shaped coils of wire arranged in the space between the side and bottom walls of the shell and the burner.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
